Integration Guide

Amplify your applications & scripts!

Integrate our API with your softwares and scripts and be more profitable by selling your apps and scripts in our Software Marketplace.

How it works?

Integrating our service to work in softwares and web applications is very easy. Just refer to you API web service document at https://api.captchas.io/document/ and walk you through integrating our service.

CAPTCHAs.IO API works by calling two endpoints, the https://api.captchas.io/in.php and the https://api.captchas.io/res.php. The https://api.captchas.io/in.php is where you submit or post the CAPTCHA data to be solved while the https://api.captchas.io/res.php is where you get the CAPTCHA solution or answer through the CAPTCHA_ID returned by the https://api.captchas.io/in.php endpoint. See parameter definitions below to start solving CAPTCHAs through this API.

CAPTCHA Solving Example:

Send an HTTP Post request to https://api.captchas.io/in.php containing the parameters:


// required parameters
$method = "userrecaptcha";
$key = YOUR_API_KEY;
$googlekey = THE_GOOGLE_SITEKEY;
$pageurl = PAGE_URL;

Parse the response of number 1 to get CAPTCHA_ID from response string "OK|CAPTCHA_ID".

Get CAPTCHA answer from https://api.captchas.io/res.php containing the parameters:


// required parameters
$key = YOUR_API_KEY;
$action = "get";
$id = CAPTCHA_ID;

Parse the response of number 3 to get CAPTCHA answer from response string "OK|CAPTCHA_ANSWER".
Done
